   • YES → Problem is remote-related
   • NO → Problem is mechanical or sensor-related
2. Check safety sensors: Are indicator lights solid (not blinking)?
   • Blinking → Sensors misaligned or blocked
   • Solid → Sensors OK, check other issues
3. Manual operation test: Disconnect opener, lift door manually
   • Door lifts easily → Opener/settings problem
   • Door very heavy → Spring problem
4. Visual track inspection: Can you see any obstructions?
   • Obstruction visible → Remove it
   • Tracks clear → Check alignment/rollers
5. Listen during operation: What sounds do you hear?
   • Grinding → Track/roller problem
   • Clicking → Potential spring issue
   • Silent, motor stops → Limit switch problem

 

How Do I Check and Fix Safety Sensor Problems?

Safety sensors are the #1 cause of garage door closing issues—and the easiest to fix.

Understanding Safety Sensors

What they do:

• Emit invisible infrared beam across door opening
• Must be within 150mm of floor
• If beam is broken during closing, door reverses
• Required by NZ safety standards since 1993

Normal operation:

• Both sensors show solid LED light (green or red depending on brand)
• Door closes without hesitation
• Breaking beam mid-close causes immediate reverse

Troubleshooting Safety Sensors

Step 1: Check indicator lights

Light Status	Meaning	Solution
Both solid green/red	Working correctly	Problem is elsewhere
One or both blinking	Misalignment or obstruction	Clean and realign
No lights	Power issue	Check wiring connections
One solid, one blinking	Receiving sensor blocked	Clean lens, check alignment

Step 2: Clean sensor lenses

1. Locate sensors on each side of door opening (150mm from floor)
2. Wipe lens with soft, dry cloth
3. Remove any spider webs or debris
4. Check if lights become solid
5. Test door operation

Step 3: Check for obstructions

• Look for anything blocking line of sight between sensors
• Common culprits: boxes, toys, garden tools, trash bins
• Even small objects can break beam
• Remove any items within 150mm of floor across doorway

Step 4: Realign sensors

How to align properly:

1. Loosen mounting bracket screws (don't remove)
2. Adjust sensor angle until both LEDs are solid
3. Use laser level for precision (optional)
4. Sensors must point directly at each other
5. Tighten screws when aligned
6. Test by closing door

Visual alignment method:

• Stand behind one sensor
• Look through its lens toward opposite sensor
• You should see the other sensor's LED directly in center
• Adjust until perfectly centered

Step 5: Check wiring connections

1. Follow wire from sensor to opener
2. Check connection at sensor (small plug/terminal)
3. Check connection at opener (terminal strip)
4. Look for damaged/pinched wires
5. Reconnect any loose wires
6. Replace damaged wire sections

Sensor Alignment Tips

Causes of misalignment:

• Accidentally bumped by vehicle
• Kids playing near sensors
• Vibration from door operation
• Settling of house/garage foundation
• Temperature changes (expansion/contraction)

Keep sensors aligned:

• Mount brackets securely
• Consider protective covers (available $20-$30)
• Educate family not to touch sensors
• Check alignment during regular maintenance

When Sensors Need Replacement

Replace sensors if:

• LED lights never illuminate (power confirmed good)
• Physical damage to lens or housing
• Water damage/corrosion visible
• Sensor older than 10 years
• Cannot achieve stable alignment

Replacement cost: $60-$120 DIY, $150-$250 professional installation

 

What If My Door Closes Part-Way Then Reverses?

This specific symptom has several possible causes.

Diagnosis by Reversal Point

Reverses immediately upon closing:

• Cause: Safety sensor issue
• Fix: Follow sensor troubleshooting (see previous section)

Reverses at 30-50% closed:

• Cause: Track obstruction or binding
• Fix: Inspect tracks for debris, bent sections, or roller issues
• Test: Manually operate door—should move smoothly through this point

Reverses at 70-90% closed:

• Cause: Down limit set too low
• Fix: Adjust down limit (see limit settings section)

Reverses right before fully closed:

• Cause: Force setting too sensitive OR floor obstruction
• Fix: Increase down force slightly OR check for uneven floor

Track Binding Issues

How to check for binding:

1. Disconnect opener (pull emergency release)
2. Manually close door SLOWLY
3. Feel for resistance or sticking points
4. Look for rollers binding in tracks
5. Listen for rubbing/scraping sounds

Common binding causes:

Bent track:

• Check for visible deformity
• Use straight edge to verify track straightness
• Minor bends can be gently hammered flat
• Major damage requires track replacement

Worn rollers:

• Rollers should spin freely
• Check for flat spots or cracks
• Listen for grinding noise
• Replace if damaged ($15-$25 each)

Dirty tracks:

• Built-up grime creates friction
• Clean with degreaser and cloth
• Wipe dry
• Light lubrication with silicone spray

Track misalignment:

• Tracks must be perfectly parallel
• Check with level
• Adjust mounting brackets if needed
• Professional adjustment may be required

Force Setting Adjustment

If door reverses due to force detection:

Locate force adjustment screws on opener:

• Usually on side or back of opener unit
• Labeled "FORCE" or "UP/DOWN"
• Typically two screws (up force, down force)

Adjusting down force:

1. Find DOWN FORCE screw
2. Turn clockwise 1/4 turn (increases force)
3. Test operation
4. Repeat if needed (maximum 2-3 full turns from baseline)
5. Don't over-adjust—door must still reverse on obstruction

Testing proper force:

• Place 2x4 wood block flat on floor in door path
• Close door
• Door should reverse upon contact with wood
• If doesn't reverse, reduce force setting
• NEVER disable safety reverse feature

 

How Do I Adjust Garage Door Limit Settings?

Limit switches tell your opener when the door is fully open or closed.

Understanding Limit Switches

What they control:

• UP limit: How far door opens
• DOWN limit: How far door closes
• Improper settings cause most operational issues

Signs limits need adjustment:

• Door stops before fully closed (down limit too high)
• Door reverses before touching floor (down limit too low)
• Door opens but hits stops with force (up limit too high)
• Door doesn't open fully (up limit too low)

Adjusting Down Limit (Most Common Issue)

Step-by-step adjustment:

1. Locate limit adjustment screws

• On opener unit (back or side panel)
• Usually two screws labeled "UP" and "DOWN"
• Sometimes labeled with arrows (↑ ↓)
• May be knobs or screwdriver-adjustable

2. Identify which direction to adjust

• Door stops too high? Turn DOWN screw to right/clockwise
• Door reverses before closing? Turn DOWN screw to left/counterclockwise

3. Make small adjustments

• Turn screw 1/4 turn at a time
• Test door operation after each adjustment
• Continue until door closes properly

4. Final test

• Door should close fully and seal against floor
• Bottom seal should compress slightly
• Door should not reverse
• Opener should stop smoothly

Adjustment range:

• Typically 10-15 full rotations possible
• Each 1/4 turn = 20-30mm of travel change
• Don't force screws past their range

Adjusting Up Limit

When needed:

• Door doesn't open fully
• Door opens too far and strains

Adjustment process:

1. Close door completely
2. Locate UP limit screw
3. Turn clockwise to reduce travel (door opens less)
4. Turn counterclockwise to increase travel (door opens more)
5. Test: Door should open fully without hitting stops
6. Verify door doesn't over-travel and strain

Modern Opener Programming

For newer openers with digital displays:

1. Access programming menu (refer to manual)
2. Select "Limit Settings"
3. Follow on-screen prompts
4. Opener may "learn" limits automatically
5. Door must cycle several times during learning

Automatic limit learning process:

1. Press LEARN or PROGRAM button on opener
2. Press wall button to close door
3. Opener monitors door travel
4. When door reaches bottom, press wall button again
5. Press wall button to open door
6. When fully open, press wall button again
7. Opener saves these as limit positions

Common Limit Setting Mistakes

Problem: Over-adjusting

• Making large turns (>1/2 turn at once)
• Bypassing safety features
• Solution: Small 1/4 turn adjustments only

Problem: Adjusting wrong screw

• Confusing UP and DOWN limits
• Solution: Note current position before adjusting, make changes one at a time

Problem: Limits constantly changing

• Indicates mechanical issue (worn gears, loose chain)
• Solution: Have opener serviced professionally

What Should I Do If the Door Won't Close From the Remote but Works From the Wall Button?

This specific symptom points to remote/receiver problems.

Quick Fixes to Try First

1. Replace remote battery (Solves 70% of remote issues)

• Most remotes use coin cell battery (CR2032 or similar)
• Battery life: 1-2 years typical
• Low battery causes intermittent operation
• Test with new battery before troubleshooting further

2. Check if remote is out of range

• Stand closer to opener (within 10m)
• Metal in garage reduces signal range
• Test from various positions
• If works only very close, antenna or receiver issue

3. Reprogram remote Standard programming:

1. Press LEARN button on opener (LED blinks)
2. Within 30 seconds, press button on remote
3. LED on opener stops blinking (programmed)
4. Test remote operation

Security+ 2.0 programming:

1. Press LEARN button on opener
2. Press and hold remote button until opener LED blinks
3. Release remote button
4. Test operation

4. Verify remote isn't locked out

• Some openers have "vacation lock" feature
• Disables all remotes (security feature)
• Check wall control for lock indicator
• Disengage lock mode

Remote Troubleshooting Table

Symptom	Likely Cause	Solution
No response, any distance	Dead battery	Replace battery
Works only very close	Weak battery or receiver issue	Try new battery, check antenna
Works intermittently	Interference or partial programming	Reprogram remote
All remotes stopped working	Vacation lock OR receiver failure	Check lock mode, reset opener
One remote works, others don't	Lost programming	Reprogram non-working remotes
Remote works for other functions	Remote button failed	Replace remote

Receiver and Antenna Issues

Check opener antenna:

• Locate antenna wire (hangs from opener)
• Should be straight down, not coiled
• Check for damage or disconnect
• Straighten if bent

Signs of receiver failure:

• No remotes work (wall control does)
• Remotes require standing directly below opener
• Recently had power surge
• Opener is >10 years old

Receiver replacement:

• Universal external receivers: $50-$80
• Professional installation: $120-$180
• Adds external antenna for better range

Interference Problems

Common interference sources:

• LED light bulbs in opener (yes, really)
• Nearby radio towers
• Other garage door openers nearby
• WiFi routers operating on same frequency

Solutions:

• Replace LED bulbs with incandescent in opener
• Try operating at different times (test interference)
• Change opener frequency if option available
• Install external antenna away from interference

When to Replace Remote

Replace remote if:

• Case is cracked or damaged
• Buttons don't click properly
• Water damaged
• Lost and need spare
• Upgrading to smart remote (keypad, smartphone)

Replacement options:

• Genuine manufacturer remote: $35-$55
• Universal remote: $25-$40
• Smartphone adapter (myQ): $100-$150
• Keyless entry pad: $80-$120

 

How Do I Check for Track Obstructions and Alignment Issues?

Tracks guide your door's movement—even small issues cause problems.

Visual Track Inspection

What to look for:

1. Obvious obstructions

• Toys, tools, debris in tracks
• Accumulated dirt/grime
• Ice formation (winter issue)
• Objects hanging that interfere with door travel

2. Track damage

• Dents or bends in track
• Rust or corrosion
• Cracks in track
• Loose mounting brackets

3. Alignment issues

• Tracks not parallel
• Tracks not plumb (vertical sections)
• Gaps between rollers and track
• Track pulling away from wall

Cleaning Garage Door Tracks

Supplies needed:

• Degreaser or all-purpose cleaner
• Rags or paper towels
• Soft brush
• Vacuum (optional)
• Silicone-based lubricant

Step-by-step cleaning:

1. Close door completely (safer to work with door closed)
2. Remove loose debris by hand
3. Spray degreaser on inside of tracks
4. Scrub with brush
5. Wipe clean with rags
6. Vacuum remaining dirt
7. Dry thoroughly
8. Apply light coat of silicone lubricant
9. Wipe excess (too much attracts dirt)

Cleaning frequency:

• Quarterly for typical use
• Monthly for dusty environments
• After construction/renovation
• When you notice increased noise

Checking Track Alignment

Vertical track alignment:

1. Use level on vertical track section
2. Should be perfectly plumb (vertical)
3. If off, loosen brackets and adjust
4. Retighten once plumb

Horizontal track alignment:

1. Measure from wall to track on both sides
2. Distance should be identical
3. Horizontal section should slope slightly toward back (helps door stay open)
4. Adjust brackets if needed

Track parallel check:

1. Measure track spacing at top
2. Measure track spacing at bottom
3. Measurements should match
4. Difference >10mm indicates problem

Professional help needed if:

• Tracks more than 15mm out of alignment
• Multiple brackets need adjustment
• Track is bent beyond minor repair
• Door binding cannot be resolved with cleaning/lubrication

Roller Inspection and Replacement

Signs rollers need attention:

• Grinding or squeaking noise
• Visible wear or flat spots
• Cracks in roller material
• Roller doesn't spin freely
• Door moves jerky/unsmooth

Checking rollers:

1. Disconnect opener (emergency release)
2. Manually move door up and down slowly
3. Watch each roller—should spin smoothly
4. Check for wobbling or binding
5. Look for damage to roller shaft

Roller types:

• Nylon rollers: Quieter, longer-lasting, $20-$30 each
• Steel rollers: Budget option, noisier, $10-$15 each
• Sealed bearing rollers: Best quality, $25-$40 each

Replacing a roller (DIY-friendly):

1. Close door completely
2. Locate hinge with roller
3. Remove bolt holding hinge (NOT near springs)
4. Slide hinge/roller assembly out of track
5. Remove old roller from hinge
6. Install new roller
7. Reinsert into track
8. Bolt hinge back in place

⚠️ NEVER remove rollers/hinges near springs—extreme danger!

 

What Are Signs My Garage Door Springs Need Replacement?

Springs are critical—and when they fail, the door won't close properly (or at all).

Signs of Spring Failure

Definite spring failure:

• ✗ Loud bang sound (spring snapping)
• ✗ Visible gap in spring coil
• ✗ Door won't lift manually (too heavy)
• ✗ Door falls rapidly when closing
• ✗ Cables hanging loose

Warning signs of imminent failure:

• △ Door harder to lift manually than usual
• △ Door uneven when opening (one spring weaker)
• △ Visible rust or corrosion on springs
• △ Door closes too quickly
• △ Opener strains (grinding noise)

Testing Spring Balance

Safe balance test:

1. Close door completely
2. Disconnect opener (pull emergency release)
3. Manually lift door to waist height
4. Release door gently

Results:

• Good balance: Door stays in place or moves very slowly
• Weak springs: Door falls toward closed position
• Over-tensioned: Door rises toward open position

If door is very heavy or won't lift:

• Springs have failed
• DO NOT attempt to use opener
• DO NOT try to force door open
• Call professional immediately

Why Spring Issues Prevent Closing

Springs counterbalance door weight:

• Average door: 60-150kg
• Springs offset 90-95% of this weight
• Opener motor only designed to move 5-10kg
• Without proper spring tension, opener can't close door

When springs weaken:

• Door becomes heavier
• Opener struggles (may burn out motor)
• Door may close partially then stop
• Safety sensors may trigger (detecting resistance)

DIY vs Professional Spring Replacement

Why professional replacement is critical:

Torsion springs (most common):

• Store 200-400kg of force
• Require specialized winding bars
• Improper handling causes severe injury
• Fatalities occur with DIY spring work

Extension springs (older systems):

• Also store significant energy
• Cable can whip if spring breaks
• Safety cables should be installed

Professional spring replacement:

• Cost: $180-$450 (see spring replacement article)
• Time: 60-90 minutes
• Warranty: 1-3 years typical
• Safe: Proper tools and training

ACC reports 50-70 garage door injuries annually—many from DIY spring work. Not worth the risk.

 

Why Does My Door Close Then Immediately Reopen?

This "close-and-reopen" behavior has specific causes.

Up-Force Setting Too High

What's happening:

• Opener's up-force is set too sensitive
• When door hits bottom, slight resistance triggers opener
• Opener "thinks" door hit an obstruction
• Opens door as safety feature

How to fix:

1. Locate FORCE adjustment screws on opener
2. Find UP FORCE screw
3. Turn counterclockwise 1/4 turn (reduces up force)
4. Test door operation
5. Repeat if needed

Testing proper adjustment:

• Door should close and remain closed
• Door should still reverse if blocked during operation
• Don't reduce force so much that safety features don't work

Down Limit Set Too Far

What's happening:

• Down limit tells opener to keep closing
• Door reaches floor but limit hasn't been reached
• Door pushes against floor
• Resistance triggers automatic reopening

How to fix:

1. Locate DOWN LIMIT adjustment screw
2. Turn counterclockwise 1/4 turn (reduces down travel)
3. Test operation
4. Adjust until door stops exactly when closed, without force

Floor Obstruction or Uneven Floor

What's happening:

• Door seal contacts uneven floor
• Creates resistance that triggers reopen
• More common after floor repairs/resurfacing

How to fix:

Minor unevenness:

• Adjust down limit slightly higher
• Accept small gap if necessary
• Install longer/more flexible bottom seal

Major unevenness:

• Grind down high spots (concrete grinder)
• Fill low spots (self-leveling compound)
• Professional floor leveling may be needed

Sensor Interference

What's happening:

• Sensor beam briefly breaks during door closure
• Sun reflection or light interference
• Causes door to reverse

How to fix:

• Shield sensors from direct sunlight
• Check for reflective surfaces near sensors
• Relocate sensors if environmental interference unavoidable

Logic Board Issues

What's happening:

• Opener's circuit board malfunctioning
• Random behavior, not consistent pattern
• Usually accompanies other symptoms

Signs of logic board failure:

• Unpredictable operation
• Works sometimes, not others
• LED lights flash error codes
• Recent power surge

Solution:

• Professional diagnostic required
• Circuit board replacement: $150-$300 parts + labor
• May be more cost-effective to replace entire opener

 

How Do Weather and Humidity Affect Garage Door Operation?

Weather impacts garage doors, especially in humid climates.

Humidity and Swelling

How humidity affects doors:

Timber doors most affected:

• Wood absorbs moisture
• Swells in humid conditions (summer)
• Shrinks in dry conditions (winter)
• Can swell 5-10mm, causing binding

Solutions:

• Proper sealing/painting prevents moisture absorption
• Adjust seasonal clearances if needed
• Dehumidifier in garage helps
• Regular maintenance (re-stain/seal every 2 years)

Steel doors:

• Less affected by humidity
• Rust can develop in high humidity
• Regular lubrication prevents corrosion

Temperature Effects

Cold weather issues:

Springs become brittle:

• Metal contracts in cold
• More likely to snap on first cold morning
• Most spring failures occur in winter

Metal components contract:

• Slight dimensional changes
• Can affect limit settings
• May need seasonal limit adjustments

Lubrication thickens:

• Grease becomes stiff in cold
• Door operates slower/louder
• Use winter-grade lubricants in cold climates

Hot weather issues:

Metal expansion:

• Door and tracks expand slightly
• May cause slight binding
• Usually resolves as day cools

Opener motor stress:

• Heat affects electronic components
• Motor works harder in heat
• Ensure garage ventilation adequate

Seasonal Maintenance

Spring/Fall transition:

• Check and adjust limit settings if needed
• Inspect weather sealing
• Lubricate all moving parts
• Test balance (spring tension may need adjustment)

Summer preparation:

• Ensure adequate ventilation
• Check opener doesn't overheat
• Inspect seals (humidity can deteriorate rubber)

Winter preparation:

• Switch to winter-grade lubricant
• Check weather seal integrity
• Test opener in cold (before freezing weather)
• Clear snow/ice from bottom seal regularly

Coastal Considerations

Salt air corrosion:

• Accelerated rust on metal components
• Springs fail faster (5-7 years vs 10-12 inland)
• Hardware deteriorates quickly

Prevention:

• Monthly rinse with fresh water
• Use marine-grade components
• Corrosion-resistant coatings
• More frequent lubrication (monthly vs quarterly)

Upgrade recommendations for coastal properties:

• Stainless steel hardware
• Powder-coated or galvanized springs
• Enclosed track systems
• Annual professional service

 

What If My Door Closes Unevenly or Crooked?

Uneven closing indicates spring or cable issues.

Diagnosing Uneven Closing

Visual test:

1. Partially close door (chest height)
2. Step back and observe
3. Door should be level (parallel to floor)
4. If one side higher than other → uneven spring tension

Measuring unevenness:

• Measure from floor to bottom of door on each side
• More than 25mm difference indicates problem
• Mild unevenness (<25mm) may be tolerable
• Severe unevenness (>50mm) needs immediate attention

Causes of Uneven Operation

1. Broken spring (one side)

• Torsion spring systems: Center spring broken, or one spring in dual-spring system
• Extension spring systems: One side's spring broken
• Symptoms: Door very heavy on one side, may bind in tracks
• Solution: Professional spring replacement

2. Uneven spring tension

• Springs installed/tensioned incorrectly
• Springs aged differently (one side wore faster)
• Recent amateur spring adjustment
• Solution: Professional spring adjustment/replacement

3. Cable issues

• One cable stretched or damaged
• Cable off drum or pulley
• Cable fraying
• Solution: Professional cable inspection/replacement

4. Track misalignment

• One track out of plumb or alignment
• Mounting brackets loosened
• Track damage
• Solution: Track realignment or replacement

Safety Concerns With Uneven Operation

Why uneven doors are dangerous:

• Door can jam in tracks
• Panels can separate
• Cable can snap (whipping hazard)
• Door could fall
• Opener motor damaged

DO NOT:

• ✗ Continue operating severely uneven door
• ✗ Attempt to adjust spring tension yourself
• ✗ Remove cables or springs
• ✗ Force door to operate

DO:

• ✓ Disconnect opener immediately
• ✓ Secure door in closed position if possible
• ✓ Call professional for inspection
• ✓ Keep people/vehicles clear of door

Temporary Fixes (Until Professional Service)

• After extreme weather events

Best Practices for Long Life

Daily habits:

• Don't hold remote button (causes strain)
• Let door fully open/close (don't interrupt cycles)
• Keep garage floor clear of obstacles
• Don't let children play near operating door

Seasonal care:

• Clear snow from bottom seal (winter)
• Check weather stripping (spring/fall)
• Test operation in extreme temperatures
• Adjust limits if seasonal changes affect operation

What to avoid:

• Never try to force door if not operating
• Don't disconnect safety features
• Don't ignore unusual sounds
• Don't delay spring replacement when needed

Signs It's Time for Replacement (Not Just Repair)

Consider full door replacement if:

• Door is 20+ years old
• Multiple major repairs needed simultaneously
• Frequent breakdowns despite maintenance
• Significant rust or structural damage
• Want to upgrade insulation/style
• Safety features outdated/missing

Replacement cost: $1,500-$8,000 depending on door type (see installation cost article)

 

Frequently Asked Questions

Why won't my garage door close with the remote but closes with the wall button?

This indicates a remote or receiver issue, not a mechanical problem. First, replace the remote battery—this solves 70% of remote-only issues. If the battery is new, reprogram the remote by pressing the LEARN button on the opener, then pressing the remote button within 30 seconds. If all remotes fail but the wall button works, check if vacation lock mode is engaged or if the receiver has failed.

Can cold weather prevent my garage door from closing?

Yes—cold weather causes metal to contract, making springs more brittle and lubricants thicker. Springs are most likely to break on the first cold morning of winter. Metal track and door components also contract slightly, which can affect limit settings. Solutions: use winter-grade lubricants, have springs inspected before winter, and make small limit adjustments if needed for seasonal changes.

How often should I lubricate my garage door?

Lubricate all moving parts every 3 months (quarterly) for optimal performance. Use silicone-based garage door lubricant on springs, rollers, hinges, and tracks. In coastal areas or dusty environments, lubricate monthly. Never use WD-40—it's a cleaner, not a lubricant, and attracts dirt. Annual professional service includes complete lubrication.

Why does my garage door opener work but the door is very heavy?

This indicates broken or severely weakened springs. The opener motor is only designed to move 5-10kg—springs provide 90-95% of the lifting force. When springs fail, the door becomes unbearably heavy. DO NOT continue using the opener as it will burn out the motor. Disconnect the opener and call a professional for spring replacement immediately.

Can I adjust my garage door springs myself?

No—spring adjustment should only be performed by trained professionals. Torsion springs store 200-400kg of force and require specialized tools (winding bars) and expertise. Attempting DIY spring work has resulted in severe injuries and fatalities. Professional spring adjustment costs $120-$180 and is completed safely in 30-45 minutes.

Why does my door close then immediately reopen?

Common causes: (1) UP FORCE setting too sensitive—reduce up force by 1/4 turn; (2) DOWN LIMIT set too far—adjust limit so door stops exactly when closed without pushing on floor; (3) Floor obstruction or uneven floor creating resistance; (4) Sunlight or reflection interfering with safety sensors. Test each possibility systematically.

How do I know if I need to replace my garage door opener?

Replace your opener if: it's 15+ years old, motor makes burning smell or grinding noises, frequent failures despite repairs, lacks modern safety features (photo-eye sensors), you want smart home integration, or repair costs approach 50% of new opener cost. Modern openers are significantly quieter, safer, and more reliable than older models.

Can I still use my garage door if one spring is broken?

On extension spring systems (paired springs), if one breaks you might still operate the door but it will be uneven and dangerous—don't use it. On torsion spring systems (single spring), if the spring breaks the door will be too heavy to operate. In both cases, disconnect the opener, secure the door closed if possible, and call a professional immediately. Operating with broken springs risks injury and property damage.
